Abstract
The problem of interaction between a nonsteady-state pressure wave and a moving interface between acoustic media is analyzed and solved for the first time with allowance for a finite displacement of the interface induced by the wave. An analytic solution is obtained using a nonlinear time transformation method. Expressions are obtained for the law of motion of the interface, and for the reflected and transmitted waves as a function of the time profile of the incident wave and the acoustic characteristics of the media.
